Experimental Demonstration of π Equivalent Phase-Shifted SBG Laser With Controlled Distributed Phase Shift [PDF]

open access: yesIEEE Photonics Journal, 2019
We designed and fabricated a π equivalent phase-shifted sampled Bragg grating (SBG) semiconductor laser with a controlled distributed phase shift. The phase shift is equivalently realized with reconstruction-equivalent-chirp (REC) technique. The laser is divided into three sections with the same length. By injecting different currents into the side and

Design of a Double-Half-Bridge Rectifier With Single-Stage and Power Decoupling

open access: yesIEEE Access, 2023
Several power decoupling techniques have been studied in the specialized literature to reduce or eliminate the ripple at 120 Hz intrinsic to the nature of single-phase AC-DC converters.

Large conditional single-photon cross-phase modulation [PDF]

open access: yes, 2015
Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by $\pi$ through interaction with only one photon.

Gate controlled anomalous phase shift in Al/InAs Josephson junctions [PDF]

open access: yesNature Communications, 2020
AbstractIn a standard Josephson junction the current is zero when the phase difference between superconducting leads is zero. This condition is protected by parity and time-reversal symmetries. However, the combined presence of spin–orbit coupling and magnetic field breaks these symmetries and can lead to a finite supercurrent even when the phase ...

Minimum Current Optimization of DBSRC Considering the Dead-Time Effect

open access: yesEnergies, 2022
In a dual-bridge series resonant converter (DBSRC) working at a high switching frequency, the dead-time effect is a serious issue. When the minimum current trajectory (MCT) method is applied, the inductor current cannot be minimized due to the dead-time ...

Duffing revisited: Phase-shift control and internal resonance in self-sustained oscillators [PDF]

open access: yes, 2015
We address two aspects of the dynamics of the forced Duffing oscillator which are relevant to the technology of micromechanical devices and, at the same time, have intrinsic significance to the field of nonlinear oscillating systems.

Robust interferometer with external phase-shift control

open access: yesOptics Express, 2017
We describe a robust interferometer with external phase-shift control that does not require moving parts. The optical architecture resembles a common-path device in which the interfering waves propagate together in one collimated beam passing through the test sample.

A Bidirectional Isolated Integrated AC–DC Converter Based on an Interleaved 3-Level T-Type Power Converters

open access: yesIEEE Access, 2021
This paper presents an integrated single-phase bidirectional ac–dc converter based on a dual-active-bridge (DAB) topology. The primary side is based on a multi-state switching cell (MSSC) with a T-type (TNPC) cell, which is composed of two three ...

Inductive Power Transfer Battery Charger with IR-Based Closed-Loop Control

open access: yesEnergies, 2022
A wireless battery charger with inductive power transfer (IPT) was proposed in this paper. The commonly used constant-current constant-voltage (CC-CV) charging method is accomplished by a closed-loop controlled IPT with a hybrid resonant circuit on the ...

Comprehensive steady state analysis of bidirectional dual active bridge DC/DC converter using triple phase shift control [PDF]

open access: yes, 2014
Several papers have been published recently on TPS control of dual active bridge (DAB) converter, however, no complete study of the converter operation behaviour exists, that takes into account all switching modes in both charging and discharging ...
